Thereceptacle .37 as thus'far describedis substantially the same 'as in my prior application but I have improved the construetion of this earlier receptacle by providing a hinged rear wall 45 which ispivotally mounted upon a cross rod 46 supported beneath the receptacle and is yieldingly held inclosedposition-by.a coiled spring 47 on the'rod.. The yielding rear lwall of there# ceptacle is of .great 'advantage' when a shut- .tleA is discharged in' improperposition, as

v l occasionally happens.v j Under these conditions the rear wallwill yieldto permit the end of a misplacedy shuttle to 'be thrustbackward, thus avoiding the breakagewhich has heretofore occurredf F'o'r the samepurpo'se' have also provided if a yieldingly`mount`ed"'guide or supportingl platen() over .vliich'the ejected shuttlep'ass shuttle. y

Under normal conditions the plate 50 remainsfsubstantially in thefposition indicated iii Fig. 1 but it'may readily yield and be swung backward if engaged by a misplaced -for certain improvements on the driving mechanism disclosed inmy prior application,

This construction is shown in Figs. 11, 12 and 13, of the drawings and comprises a tension spring V secured at one end to a iiiredlug or bracket 61 andl at the opposite end to a projectionl 62 von an upwardly extendingarm 63 of the vbelt crank 6 4 by vwhich the. clutch pinion 65 shaft'166. The rarm 63 is forked at its upper end lto receive studs 67 on` a yoke collar by f which the pinioiris engaged. rllie lugs or projections 61 and 62 are so positioned that the fspring 60' will be disposed Y at opposite y'sidesof theaXis yof the vbell crank 64 inthe two positionsshownin Figs. 12'and13, thus .having a toggle action to yieldingly. prevent Vdisplacementof thegpaij'ts. 5

A VThe general 'construction and operation of scribed in my prior application above noted description thereof. Having thus described'myinvention, 'I do not wish'tobe limited to the details herein disclosed otherwise than as s claims but what I claim is:-

l. in a shuttle changing loom, ashuttle transfer receptacle and elevating mechanism and reference is made thereto'for a complete Y et forth' inthe my improved loom is fully `disclosed .and'dev therefor, said receptacle having its back wallk mounted for rearward yielding movement to Vprevent damage from a misplaced shuttle.

V2. In a shuttle changing loom, a shuttle transferreceptacle, a shaft mounted thereon, said receptacle having its back wall pivoted on said shaft, anda spring to move said wall yieldingly'to closed'position.v f

3. ln a shuttle changing loom', a"lay,1shift ing shuttle' boxes thereon,'fa spent shuttle storage, a movable shuttle transfer recepico tacle effective to transfer spent' shuttles to Y said storage, and' means to' guide ashuttle yfrom, said 'lay to said transfer receptacle, said meansincludinga guidev plate inter-v posed between said lay and said transfer receptacle at the rear'of said lay, andmeans to hold saidplate yieldingly in position.l
